Migrate away from SiteGround

Hello,

A client of mine is using SiteGround’s hosting and Cloudflare. All his DNS records are in SiteGround’s panel.

He bought the PRO plan for Cloudflare and asked me to migrate his site. I don’t know what to do with the DNS records since they are stored in SiteGround’s panel, not in Cloudflare. Furthermore, Cloudflare does not allow to create a duplicate domain since the original already exists but cannot be managed directly.

Thank you in advance,
Giannis
